Calibration of gas meters

Most utilities use 7" of water column (w.c.) for residential gas meters. I was told that when the gas pressure regulator goes below 7" w.c., the customer pays more and when the gas pressure regulator goes above 7" w.c., the utility loses money. I recently had my gas meter replaced and my regulator was at 4" w.c.. Does anyone know how to calculate how much gas I was really getting using a "sprague" bellows type gas meter?

Answer From: Lance Schafhausen Energy Economics,Inc. Gas Meter Prover Development Division.

If you consider the way standard diaphragm meters are made, when accurately calibrated using conventional vacuum sonic nozzle provers or positive displcement bell provers, residental gas meters will index actual flow at minimal pressures leading up to maximum recommended pressure for that meter.. I'm sure there is a minimum requirement, I'm sure it varies from meter to meter. Pressure does effect flow rates, but the diaphragms inside the meter will act accordingly. going below 7"wc should not affect the accuracy of the meter. The index of the meter should indicate accurate flow. If you meter is in question, contact your utility company and request a meter accuracy statement. In some cases this may cost you , or may not be possible without filing a dispute of your bill or in a case of a meter failure.

Missing section

There is no section in this article explaining how prepayment meters work, ie how do the meters know the price of gas? FreeFlow99 (talk) 09:52, 19 October 2021 (UTC)[reply]
